ALARM-CLOCK.

Specification of Letters Patent.

Patented lvlay '7, 1907.

Application filed September 4. 1906. Serial No. 333.111.

To 1.11/7 w/wm, it may concern.-

Be it known that we, ELMER E. SrooKroN and ARTHUR 'H. PORTER, citizensof the United States, residing at Bristol, in the county of Hartford andState of Connecticut, l'iave invented a new and useful lmprovement inAlarm-Clocks and we do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1 a plan view of a nickel alarmclock constructed in accordancewith our invention. Fig. 2 a view of the clock in vertical flatwisesection on the interrupted line ab of Fig. 3, looking into the front ofthe clock upon the dust-guard which is exposed by the removal of thebell. Fig. 3 a view in vertical crosswise section on the irregular linec-d of Fig. 2.

Our invention relates to an improvement in nickel alarm clocks, socalled, this name having long been applied by the trade to small alarmclocks in circular nickeled sheetmetal cases. In recent years theseclocks .have been provided to a large extent with concentricallyarranged bells located at the back and perforated for the passage of thewinding and setting arbors. Such clocks are objectionable in so far asthe bell is exposed, and as they call for long winding and settingarbors, and special packing boxes, all entailing extra expense.

The object of our invention is to obviate these objections and toproduce a simple,

compact and effective clock in which the bell is completely protected,and in which the back of the clock is left as in nickel alarm clockshaving the bell located on top of the case.

With these ends in view our invention con sists in locating a concentricbell entirely within the clock case and in certain details ofconstruction as will be hereinafter described and pointed out in theclaims.

In carrying out our invention, I employ a bell 2 arranged concentricallywithin the circular case-body 3 and located at a point between the dial4 and. the front plate 5 of the clock-movement which may be of any approved construction and is not shown beyond its said plate 5, its rearmovement-plate 6 and its pillars 7. These parts sufficiently show itsposition in the case-body and its relation to my present improvement.

To permit the sound of the bell to escape, we form a series ofperforations in the case in proximity to the bell. As shown, theseperforations take the form of a band of circular holes, but it is notnecessary that there should be a continuous band of perforations, orthat they should have one form rather than another. Nor is it essentialthat they should be used at all, but by preference they will be used insome form or other.

The hell 2 rests upon a circular bearing face 9 forming the truncatedtop of large concentric conical boss 9 struck forward from the center ofa circular sheet-metal dust-guard 10 corresponding in diameter to theinternal diameter of the case-body 3 and designed to prevent any dustthat may work through the perforations 8 from getting into the movementwhich is located entirely back of this guard. As shown, the bell issecured to the said guard 10 by means of three fixed screw studs 10carried thereby and receiving nuts 11 which bear upon the outer face ofthe bell, as shown in Fig. 2. These screw studs are made just right inlength to support the center of the dial 1 as also shown in Fig. 2.

The dust-guard itself is fastened by screws 12 or by rivets as the casemay be, to the radial inner ends of three stiff sheet-metal strap-likefeet 13, 14, 15, employed to position and hold the movement in thecase-body 3. The upper strap 13 is secured. by a rivet 16 directly tothe front movement plate 5, while the lower straps 14- and 15 areriveted to the forward ends of the two lower pillars 17 of the movement.These feet extend horizontally forward at their outer ends and areattached to the case-body 3,-the upper foot 13 by the stem 18 of thehandle ring 19,

and the feet 14 and 15 by the turned peglike feet 20 and 21. At theirextreme forward ends the feet are bent inward to form bearing-flangesfor supporting the dial L which is held in place by a bezel 23supporting a glass 24 held in place by turning in= ward the forward edgeof the case-body 3 to form a retaining flange 25. A clearance opening 25is formed in the dust-guard 10 to permit the hammer 2 and hammer-tail 23to reach forward from the clock-movement TOO to the bell. The back 29 ofthe case fits into the open rear end of the ease-body 3 in the usualway.

By locating the bell eru' irely within the case-body, we conceal andprotect it and restore the exterior form of the ease to its originalaspect. We also avoid making the winding and setting arbors of theexpensive and ineonvenien t length demanded when the bell is located onthe back of the case, and also reduce the mutilation of the hell itselfto the mininmm. :l urthernmre our improved clocks do not require thespecial boxes called for when the bell is at the back.

1. ln an alarm clock, the combination with a circular case-body formedwith perlbrations, of a movement and a dial, a concentrically arrangedbell located between the dial and the front of the movement, and adust-guard located within the case in front of the movement to isolatethe same from the perforations in the case.

2. In an alarm clock, the combination with a circular case-body, of amovement, a dial, a concentrically arranged bell located between thefront of the movement and the dial, and a lust-guard located between thehell and the movement and supporting the 0 bell.

ln an alarm clock, the combinaiion w'th a circular body, of a movmnent,feet attached thereto for positioning the same within the case, a dial,a dust-guard applied to the said feet, and a concentrically arrangedbell located between the dust-guard andv the dial and carried by thesaid guard.

4:. In an alarm. clock, the combination with a circular case-bod y, of amovement, a. dial, a dust-guard, a concentrically arranged bell locatedbetween the dial and the dustguard, and screw studs mounted in thedustguard and supporting the said hell and also supporting the centralportion of the dial.

5. In an alarm clock, the combination with a sheet-metal ease-bodyformed in its ftn'ward portion with perforations, of a movement, a belllocated within the casebody adjacent to the said perforations and infront of the said movement, and a dial formed independently of the belland located in front of the same.

in testimony whereof, we have signed this specification in the presenceof two subscribing witnesses. 4
